Technical field
The utility model relates to be surface-treated and technical field of sewage, in particular to a kind of chromium solution recovery system.
Background technique
It is exactly to be plated on the surface of metal or other materials product using electrolysis principle that (Electroplating), which is electroplated,
The process of the other metal or alloy of a thin layer can make the surface of metal or other materials product adhere to one layer of metal by plating
Film improves wearability, electric conductivity, reflective, corrosion resistance and having improved aesthetic appearance etc. so that playing prevents metal oxidation (as corroded)
Effect.Therefore, electroplating technology is widely applied in mechanical, hardware and electric appliance etc. process of producing product.Plating is national economy
Develop indispensable industry, plating pollution on the environment problem can not be ignored, and the plating disposal of three wastes is extremely urgent.
Plating is carried out in electroplating bath, and the ingredient view coating of the electroplate liquid in electroplating bath is different and different, but contains
It is provided with the main salt of metal ion, the complexing agent that metal ion in main salt forms complex compound can be complexed, be used for stablizing solution soda acid
The buffer of degree, anode activation agent and special additive (such as brightener, grain refiner, leveling agent, wetting agent, stress elimination
Agent and fog inhibitor etc.).Electroplating process is metal ion in plating solution under the action of external electric field, is reduced into metal through electrode reaction
Atom, and in the process of the enterprising row metal deposition of cathode.Therefore, it includes mass transfer in liquid phase, electrochemical reaction and electricity knot that this, which is one,
Brilliant and etc. metal electrodeposition process.
Wherein, trivalent chromium plating solution is on one of an important factor for tolerance of metal impurities ion is its industrialization of influence.
When the metal impurities ion in plating solution is more than that it tolerates the limit, plating solution has to be pocessed, and otherwise just will affect normal work
Make.
